Specification of Letters Patent.

Application filed June 18. 1913. Serial No. 774,385.

To all whom it may concern:

Be it known that I. THOMAS J. LITLE, Jr., a resident of Woodbury, in the county of Gloucester and State of New Jersey, have invented a new and useful Improvement in Opaque Reflectors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional side elevation, showing an inverted incandescent gas lamp provided with my improved reflector, and Fig. 2 is a top plan view of the reflector. Fig. 3 is a view similar to Fig. 1, showing another form of the invention, and Fig. 4.- is a side elevation of the metal neck for supporting the sheet or reflector.

My invention relates to opaque reflectors or shades used on depending lamps and may be applied to inverted incandescent gas lamps, electric lamps or any other source of light.

Where opaque reflectors are used in place of glass reflectors on account of the liability to breakage of the latter, they have produced a dark and gloomy ceiling, as the light does not pass through the shade. This is also true as to the upper side walls, there being an objection to the opaque shade on account of this darkening of the upper portions of the room.

My invention overcomes this difficulty and it consists in providing an opaque reflector with holes cut in its upper portion and arranged to allow a portion of the light to pass therethrough and thus avoid the eifect of gloomy ceilings, particularly in factory and mill lighting, and other places where opaque reflectors are used.

In Figs. 1 and 2 of the drawings, in which I show my invention as applied to an inverted incandescent gas lamp, 2 represents the inverted burner, 3 the mixer tube and 4c the mantle. These parts may be of the usual construction. The opaque reflector or shade 5 is preferably made of metal, and may be enameled or otherwise finished on either or both sides. In its upper portion, I provide a number of circumferentially inverted slots 6, separated by spider arms 7, which connect the upper rim portion 8 with the remaining portion of the reflector body. These holes or piercings may be of any desirable shape or number.

I have shown this reflector as supported on the metal neck 9 (Fig. 4;) disclosed in my Patent No. 961,504, dated June 14th, 1910, this neck having an outwardly flared flange 10 to be engaged by the burner screws or other fastening means on the burner. The metal neck may be secured to the reflector by the prongs or clips 11, which may be bent or sprung out after the metal neck is inserted from below. Where the separate metal neck is used to simplify and reduce the cost of the article, the metal neck and reflector will be assembled at the factory and sold as one article, the two parts being con nected by the prongs or other detachable securing means.

In Fig. 3 I show a form similar to that of Figs. 1 and 2, except that instead of the set screws 12 for holding the metal neck, I show a spring ring-holder 13 for this purpose. In both cases the spring ring-holder or the set screws engage the recessed portion of the neck flange to support the neck and shade. In this figure parts similar to those of Figs. 1 and 2 are marked with similar numerals with the letter a applied.

The advantages of my invention result from admitting a portion of the light to the ceiling and upper parts of the room, thus avoiding gloomy and unattractive ceilings.

The reflector is attractive in appearance and simple and relatively cheap to make.

Glass or other transparent or translucent material may be used in the holes of the reflector or shade, and many changes may be made in the size and shape of the opaque reflector as well as in its holes, method of supporting, etc., without departing from my invention.

I claim:

1. The combination with a lamp body, of a light-emitting body supported therein and an opaque globe or shade supported thereby, said shade having an annular row of openings below its upper edge and extending below the upper portion of the light-emitting body to allow a portion of the light to pass laterally and upwardly to the upper portion of the room, substantially as described.

2. An inverted incandescent gas lamp having a body portion, a mantle supported by the burner, there being a plurality of draft openings in the body above the mantle, and an opaque globe or shade supported by the burner body, said shade having a plurality of openings below its upper edge, said openings extending below the upper portion of the mantle and arranged to allow a portion of the light from the mantle to pass laterally and upwardly to the upper portion of the room; substantially as described.

3. As a new article of manufacture, an opaque reflector or shade having a row of circumferential slots in its upper portion to allow a portion of the light to pass to the ceiling and upper part of the room, and a separate metal neck connected to the upper 10 end of the shade, the neck having an outwardly extending flange arranged to be engaged by the shade holding members of the light holding fixture; substantially as described.

In testimony whereof, I have hereunto set 15 Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, 1). c."
